Procedure

A mixture of ethyl P-ethyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenoxymethylphosphinate (4.7 mmol) and phosphorus pentasulfide (1.2 mmol) is heated to 150°-160° under nitrogen for 3-4 hours. After cooling, the residue is purified by prep. TLC to give O-ethyl P-ethyl-2-nitro-5-(2-chloro-4-trifluoromethylphenoxy)phenoxymethylphosphinothioate.
